... 10) Two identical blocks, A and B are sliding along sliding along a frictionless, level table at velocity v when they each encounter a rough surface such that each has the same coefficient of friction, μ, with the blocks. Block A encounters the rough surface for 10 cm, yet is still moving at vA, and ...
